rlm@31 13 Here are the jMonkeyEngine "Hello" programs translated to clojure.
rlm@34 14
rlm@34 15 * Hello Simple App
rlm@23 16 Here is the hello world example for jme3 in clojure. It's a more or
rlm@23 17 less direct translation from the java source [[http://jmonkeyengine.org/wiki/doku.php/jme3:beginner:hello_simpleapplication][here]].
rlm@0 18
rlm@0 19 Of note is the fact that since we don't have access to the
rlm@306 20 =AssetManager= via extending =SimpleApplication=, we have to build one
rlm@0 21 ourselves.
